Roberts has been undergoing treatment for MDS, a rare blood and bone marrow disorder and has been on medical leave since the end of August.

Last week, Roberts did a "dry run" -- getting up, getting her makeup and hair done to see how her body reacts to her resumed schedule. Apparently, all went according to plan and a date was set for her return.

Roberts had a bone marrow transplant in September -- a risky procedure that left her weak and vulnerable to infection.
